Cam and crank sensors must be gapped right. The hold down is sloted so it can be moved closer or further away. New sensor should have come with a small felt pad on the end. Push the sensor in until it stops. If the gap is to much you may get an internmitent spark. ( I have also gotten bad cam sensors right out of the box)

SOURCE: car has no spark or injector pulse(new ecm,crank sensor)

Check the fuse for the injectors, some vehicles have the injectors and coil running on the same circut, at the same time check the fuse for the ignition.

SOURCE: 1999 dodge caravan new pcm new crank and cam

If you have replace new cam sensor with no sparks and the coil are good putting out 12 volt, my guess would be the computer it self faulty. cam sensor sense the cam turning and send info to computer telling computer to disperse the charge from the coil pack to the plugs assuming relay, cam sensor, coil, plugs, and wires are good. make sure the cam sensor is put in properly and position.

No start


Okay, lets start with fuses, check all your fuses, then move on to scanning the computer for any stored codes, like pcm codes as chrysler has had computer problems, and make sure power wire from battery to fuse/ relay box is good and clean, then check your auto shut down relay maybe swap with a known good one, then last dis connect all injectors and check for a shorted one.

Test at the spark plug if you are getting current there with a cheap spark plug tester, if not, it could be the spark box. ( it used to be an ignition coil on older cars ) double check the computer for codes which may lead to a cam sensor not giving the PCM information.

I HAVE A 2005 DODGE CARAVAN I WAS GOING DOWN THE ROAD AND IT JUST STALLED. THE FUEL PUMP COMES ON BUT THE ENGINE DOESNT START..


If you have good fuel pressure. Check for spark at any plug while cranking, If no spark, also place a screw driver on an injector and listen to it while someone cranks it over. If you have NO spark and NO injector click - crank sensor needs to be replaced. 95%
other 5% hmmm wiring problem on / near crank or cam sensors, theft system active, dead pcm.......

WONT START WHEN COLD CRANKS FINE. HAS CODE 54 CAM


ok, any obd code means the sensor concerned is not detected by the ecu, or is way out of range of the normal signal the ecu expects. I would therefor check the electrical path between the sensor and the ecu terminals, it may be just a chafed cable or wire.

Check MAP sensor. If PCM gets wrong data from MAP sensor it should offset ignition timing and/or make fuel mixture too lean or too rich.
